Best Vitamin D Supplements: Top 5 Products Recommended By Expert Websites

Did you know that something as simple as supplementing your diet with Vitamin D could lead you to feeling happier and healthier? Vitamin D is responsible for calcium absorption in the gut, in addition to reduction of inflammation, cell growth, immune function, and metabolism regulation. Unfortunately, few foods naturally contain the amounts of Vitamin D that we should be regularly getting, so what are the best ways to meet this daily (and critical) dietary need?

Several studies indicate that Vitamin D keeps the body in check, leading to good bone health, muscle strength and possible protection against cancer and type 2 diabetes, according to the Centers for Disease Control and Prevention. 

Feeling blue? A recent study by international researchers finds that vitamin D may even reduce depressive symptoms in adults. Results from the meta-analysis reveal that vitamin D supplementation is more effective than taking a placebo for lowering depressive symptoms. Researchers say the typical daily supplement contains 50 to 100 micrograms of vitamin D. 

Other research suggests that the kind of Vitamin D is equally as important, with a study finding that  vitamin D3 may balance the immune system and bolster defenses against viral infections. The conclusions in the mentioned study are based on observations made during a 12-week experimental period in which participants took either a D2 or a D3 supplement daily. The research team looked at how the two varieties of vitamin D influenced the activity of genes in participants’ blood. 

Unfortunately, taking too much Vitamin D can also work against us, leading to possible overdose and illness. With so many options on the health market and unclear guidance, this begs the question: what is the best way to supplement your diet with Vitamin D for the healthiest results? StudyFinds is here to help. For our findings, we visited 10 of the leading expert websites to see which Vitamin D products were rated the highest. Our list is ranked based on the most-recommended Vitamin D supplements across these sites.

The List: Best Vitamin D Supplements, According To The Experts 

1. Nordic Naturals Zero Sugar Gummies 

Who doesn’t love eating a gummy to get in their daily dose of Vitamin D? Nordic Naturals makes it easy with their beloved sugar-free gummies, letting you enjoy your sweets while avoiding all the junk. 

“If you’re trying to reduce your sugar intake, opt for Nordic Naturals’ sugar-free vitamin D3 gummy, which is sweetened with xylitol and colored with fruit and vegetable juice,” Healthline writes. “In addition to being vegetarian and non-GMO, it’s third-party tested for purity.”

Nordic Naturals is a great choice for those looking for once-a-day supplements with a pleasing, all-natural flavor. 

“The report shows the potency, purity, and freshness details of each bottle. This level of transparency shows the company’s commitment to high standards,” Sports Illustrated writes.

2. Nature Made Softgels

Nature Made has made a huge name for itself in the vitamin industry, offering amazing quality at an affordable price point. If you’re looking to start adding Vitamin D to your diet but don’t want to break the bank, this is a great place to start.

“Its softgels containing 2000 IU of vitamin D3 currently cost less than $6 for a 90-day supply and have earned USP verification — a third-party certification that attests to the product’s quality in terms of manufacturing and ingredients,” Insider writes.

The brand also offers Vitamin D in a variety of doses, so if you’re someone who has vitamin deficiency, the line of products is sure to meet your needs.

“Vitamin D3, like Vitamin D2, is a kind of vitamin that may be obtained from food. Although both forms are found in food (as Vitamin D2 and Vitamin D3), Vitamin D3 is more effective at boosting and maintaining adequate levels of Vitamin D in the body,” Discover Magazine writes.

3. NOW Foods 

If you’re someone who is in need of a high-dose supplement, NOW Foods is a great option.

“This highly-absorbable and high dose vitamin D3 supplement is perfect for those who severely lack sun exposure and have been advised by doctors to take these in order to ensure adequate supply of vitamin D,” Glamour Magazine writes.

Each tablet contains organic extra virgin olive oil and is free of allergens such as yeast, wheat, gluten, soy, corn, milk, egg or seafood.

“NOW uses Underwriters Laboratory-certified facilities, offers a good price point, and has thousands of 5-star reviews on Amazon. The brand is GMP-certified and uses the UL facility for third-party testing,” Insider writes.

4. Thorne Liquid Drops 

Thorne offers Vitamin D in liquid drops and is highly rated for its high-quality ingredients and easy use. 

“You may notice that most vitamin D supplements on the market are D3,” Healthline writes. “That’s because vitamin D3 is more potent and better absorbed than vitamin D2. It’s professional-grade and the tiny capsules are so easy to take. It also doesn’t contain lactose or preservatives.”

Thorne’s expert concoction is particularly well-rated due to its combination of Vitamin D3 and Vitamin K, which makes for a powerful blend that supports calcium levels and bone growth.

“Vitamin D drops are another convenient way to get your daily dose of vitamin D,” Sports Illustrated writes. “They’re great for the elderly or children with chewing or swallowing problems. Thorne’s supplement drops can also be added to food or mixed into beverages. Thorne’s D/K2 product is all-natural, gluten-free, and dairy-free.”

5. Ritual Multivitamin

Though Ritual’s multivitamin is not purely Vitamin D, experts say it’s a great choice for those who are looking to add Vitamin D as part of their everyday multivitamin.

“All of its adult multivitamins contain 2000 IU of vitamin D3 along with a blend of other vitamins and minerals targeted to the common health needs of each demographic,” Insider writes.

Ritual is the preferred brand for many due to its simple and vegan ingredients, holistic approach and convenient subscription plan.

“Ritual provides detailed information on ingredient sourcing and uses a third-party lab to test each product twice for contaminants,” Healthline writes. “These capsules are also vegan, non-GMO, and free of major allergens, artificial colors, and fillers.”

  1. I was put on vitamin D several years ago. Took it just like I was supposed to maybe missing a few times but not often because everyone said how important vitamin D is. Well now I am paying for it I went for a blood test as I had to change Dr. The first thing I was told after they got the results was no vitamin D for 3 months because mine was way to high. I can’t even have anything that says with vitamin D. When I looked up the symptom of Vitamin D toxicity it was very scary.
